As the scientist who helped eradicate smallpox he certainly know a thing or two about extinction.

And now Professor Frank Fenner, emeritus professor of microbiology at the Australian National University, has predicted that the human race will be extinct within the next 100 years.

He has claimed that the human race will be unable to survive a population explosion and 'unbridled consumption.’

Fenner told The Australian newspaper that 'homo sapiens will become extinct, perhaps within 100 years.'

'A lot of other animals will, too,' he added.

'It's an irreversible situation. I think it's too late. I try not to express that because people are trying to do something, but they keep putting it off.'

Since humans entered an unofficial scientific period known as the Anthropocene - the time since industrialisation - we have had an effect on the planet that rivals any ice age or comet impact, he said.

Fenner, 95, has won awards for his work in helping eradicate the variola virus that causes smallpox and has written or co-written 22 books.

He announced the eradication of the disease to the World Health Assembly in 1980 and it is still regarded as one of the World Health Organisation's greatest achievements.

He was also heavily involved in helping to control Australia's myxomatosis problem in rabbits.

Last year official UN figures estimated that the world’s population is currently 6.8 billion. It is predicted to exceed seven billion by the end of 2011.

Fenner blames the onset of climate change for the human race’s imminent demise.

He said: 'We'll undergo the same fate as the people on Easter Island.

'Climate change is just at the very beginning. But we're seeing remarkable changes in the weather already.'

'The Aborigines showed that without science and the production of carbon dioxide and global warming, they could survive for 40,000 or 50,000 years.

‘But the world can't. The human species is likely to go the same way as many of the species that we've seen disappear.'

Retired professor Stephen Boyden, a colleague of Professor Fenner, said that while there was deep pessimism among some ecologists, others had a more optimistic view.

'Frank may well be right, but some of us still harbour the hope that there will come about an awareness of the situation and, as a result the revolutionary changes necessary to achieve ecological sustainability.'

Simon Ross, the vice-chairman of the Optimum Population Trust, said: 'Mankind is facing real challenges including climate change, loss of bio-diversity and unprecedented growth in population.'

Professor Fenner's chilling prediction echoes recent comments by Prince Charles who last week warned of ‘monumental problems’ if the world’s population continues to grow at such a rapid pace.

And it comes after Professor Nicholas Boyle of Cambridge University said that a 'Doomsday' moment will take place in 2014 - and will determine whether the 21st century is full of violence and poverty or will be peaceful and prosperous.

in the last 500 years there has been a cataclysmic 'Great Event' of international significance at the start of each century, he claimed.

In 2006 another esteemed academic, Professor James Lovelock, warned that the world's population may sink as low as 500 million over the next century due to global warming.

He claimed that any attempts to tackle climate change will not be able to solve the problem, merely buy us time.

YOU ARE ABSOLUTLY RIGHT THE HUMAN RACE IS DOOMED. THE DEFINTION OF HUMAN IS AS A LIMITED CREATURE, RESEMBLING A MAN. NOT A MAN. IF A MAN CLAIMS TO BE A HUMAN YOU ARE AUTOMATICALLY IN SLAVERY. BUT IF YOU CLAIM TO STAND AS A MAN PART OF MANKIND THEN AND ONLY THEN CAN YOU CLAIM THE FREE GIFT OF GRACE PROVIDED BY JESUS CHRIST. BY ACCEPTING THE BAPTISM OF THE FATHER IN HEAVEN, THE SON AND THE HOLY SPIRIT, NOW YOU ARE FREE

His arguement is good, but I think in 100 years the Human Species will be out of this planet. We accomplish great things in only a decade, every decade we have some kind of new awakening, a new phase. 100 years, that's 10 new phases, lots of new things.

Wonder what the next generation will do, think about it.

If anything, we will all die before the 100 years with all this bullshit technology some companies make.

So? Are you afraid of death? You are all so funny! Its awesome to see such amazing creativity. If all the users of GLP get together and write a book I will buy it even if it cost $1000. Life is and will never end. But we do need a break. So I cant wait for the Universe to rest.

Why so serious? Its only a game of hide and seek. You cant have life without death. Its time for rest anyways. Its getting quite boring already. Dont you see that we can never cease to exist. We are existence. We are all God. There is no heaven or hell in the future. Its now or never. Relax. Have fun. Or not. Your choice. Either way I think its fantastic. I do hope 2012 is the end.
